In Figs. 1 and 2 of the drawings the connecting rods 30 of thedevices.26 and 21 extend downwardly, and the connectors 34 of saiddevices 26 and 21 extend upwardly. The lower end of each connecting rodof each device 26, 21 is oscillatably secured, as at 52, for pivotalmovement inra vertical plane, to a belled lower portion 53 of the lowerbarrel 22, and the upper end of each connector of each device v26, 21 isoscillatably secured, as at 54, for pivotal moverment in 4a verticalplane, upon the cross pin 2| which pivotally supports the intermediatebarrel 2U upon the upper barrel I9 of the uptake pipe or conduit I8. Thedevices 26 and 21 are disposed at diametrically opposite sides of theuptake pipe or conduit I8, and the oscillatable connections, at 52,between the connecting rods and the belled lower portion 53 are actuallybetween said connecting rods and a cross pin 55 which Vpivo-tallysupports a locomotive smoke stack engaging element 56 upon and withinsaid belled lower portion 53. The upper end of said element 56 desirablysnugly engages the inner wall of the belled lower portion 53 to providea slidable, preferably close fit between thelower barrel 22 and theelement 56 no matter what may be their relative positions. Said smokestack engaging element 56 is hollow and includes a at lower end 51adapted to be rested upon the upper end of the smoke stack of alocomotive.

The apparatus includes mechanism, denoted 'generally at 58, for swingingthe intermediate and lower barrels 20 and 22 longitudinally of thelocomotive having the smoke stack I6 thus to cause the lower barrel 22to be brought into vertical alinement with said smoke stack so that thiscan be placed in communication with the uptake pipe or conduit I8 of theapparatus at variable locations in the vicinity of the apparatus.

The swinging mechanism 58 incorporates as a part thereof acylinder-with-piston device 59 constructed in the manner as described inconnection with the disclosure of Fig. 3 of the drawings.

Said mechanism for swinging the intermediate and lower barrels of theuptake pipe or conduit I8 also incorporates a multiple-valve unit 66which is substantially like the multiple-valve unit described inconnection with Figs. 7, 8 and 9.

The pipe `connection 43 leads by a branch 6I from the source of 4supplyof fluid under pressure to the port 38 of the multiple-valve unit 60,and the pipe connection 44 leads by a branch 62 from the port 49 of saidmultiple-valve unit 60 to said container for 4iluid whence the uid canreturn tosaid source of supply. A pipe connection 63 extends between theport 39 of the multiple-valve unit 66 and an opening A32 in the upperportion of the elongated cylinder of the cylinder-with-piston device 59,and a pipe connection 64 extends between the port 4I of saidmultiple-valve unit 60 and an opening 32 in the lower portion of saidelongated cylinder of said device 59. The pipe connection 63 includes a.normally looped or bent, ilexible portion 65 thereof adjacent the device59, and the pipe connection 64 includes a similar flexible portion 66.The exible portion 65 is connected directly to the opening 32 adjacentthe upper end of the elongated cylinder of the device 59, while theflexible portion 66 is connected toa part 6,1 of the pipe connection 64which 'extends downward'` A, horizontal shoulder 19 and aboveandfpartially below said horizontal shou1 opening 32 adjacent the lowerend of ,said elonf gated cylinder of said device 59. The Abranches '6Iand 62 and the pipe vconnections 63 and. 64

are of course rigid with .the multiple-.valvev unit 6I), and said pipeconnections v63 and 64 arealso vrigid withv the cylinder-with-pistondevice '559. The proper relative positions of the parts of the lpipeconnections 63 and 64 can be 'insured in any ordinary or preferredmanner. f

In'Fig. 1 of the drawings, the connecting rod,

denoted 68, of the device 59 extends downward.'- ly, and the connector,denoted 69, of said device 59 extends upwardly. The connecting rod 68 isequivalent to theconnecting rod 30 and the connector 69 is equivalent tothe connector 34. The lower end of said Vconnecting rod 168 isoscillatably secured, as at 10, for pivotal move'- ment in a verticalplane, to an annular" metal strap 1I surrounding and rigid with4 the.`lower end portion of the intermediate barrel r2|),.a'nd the upper end ofthe connector 69 is oscillatably secured, as at 12,for pivotal movementin a vertical` plane, upon an eye member 13 rigid with Athe round houseroof. The cylinder-withepiston device 59 slants downwardly from thegeneral location of the round house roof to the lower :portion of theintermediate barrel 20 of the uptake 'pipe or conduit I8, and saiddevice 59 is disposed longitudinally of thetrack which supports thelocomotive having the smoke stack I6, directly above said track. 1f

The apparatus includes mechanism, denoted generally at 14, forreleasably retaining the lower barrel 22 of the uptake pipe or conduitI8 in an elevated, inoperative position. The mechanism 14 is clearlydisclosed in Figs. 1, 2, 4, 5 'andY 6 of the-drawings. i Said mechanism14 includes a supporting bracket member or stirrup 15 which is rigidlyxed, Vas by welding or otherwise, to the annular metal strap 1I, and asupported bracket member or -stirrup 16 which is rigidly secured', as at11, to an outer, upper surface of the belled lower portion 53 of thelower barrel 22 of the uptake pipe or conduit I8. i f The bracket memberor stirrup 15 includes a flat, generally rectilinear slab of metalcontiguous with the annular metal strap 1I vhaving an integral thickenedlower portion 18 providing an upwardly facing, horizontal shoulder 19adjacent a lower part of an outer surface of said bracket member orstirrup 15. The outer surface of, the thickened lower portion 18 isbeveled, as indi-'- cated at 86, to slant inwardly and downwardly fromthe outer end or edge of the upwardly facing, horizontal shoulder 19tothe lower end of .the bracket member or stirrup 15. Said outer end oredge of said horizontal shoulder 19 is parallel with the outer surfaceof the upper portion of the slab of metal which said bracket member orstirrup 15 includes, and the beveled surface lies in an oblique planeincluding the outer end or edge of the horizontal shoulder 19. Op'-positely disposed retaining and guiding elements 8| are integral orrigid with the opposite side edges of the bracket member or stirrup 154and extend in direction longitudinally of said bracket member orstirrup, away from the annular metal strap 1I and toward each other.More explicitly; each retaining and guiding element 8| is constructed toprovide an L-shape guideway 8,2 which is contiguous, with the upwardlyfacing', is disposed partially der at the outer side of the bracketmember or` stirrup 15,'and the guideways 82 are in opposed, facingrelation to each other. An upper portion of each retaining and guidingelement 8| is. constituted as vantupwardly extending resilient arm 83which is rigid withthe corresponding retain` ing and guiding element atits lower portion and is freeat its upper portion. The resilient arms 83aredisposed at. the side of the bracket member or stirrup opposite the.annular metal J,strap/1I infront o and adjacent opposite side -portionsof lthe upper part. of the. outer surface of said .bracket member orstirrup 15.. Thatis, ,thereis a resilient arrn83 directly above each nottheresilient arms. 88 normally are, engaged .against the outer surfaceof the bracket: member Desirably, the .upper or f ree ends' Ylcwerportion `t?, ci the lower barrel. 2.2 or the -uptake pipe,orconduit and the. upper end por,-

`. tion of said bracket member or stirrup 16 is bent .to provide adownwardly facing, horizontal shoulder SLi-at the side of the strip of.metal ad.- jacentthe .thickened portion 18 .of the bracket member.crstirrup 1,5 and a beveled suriaoe 85 slanting inwardly and downwardlyfromthev upper end of the bracket member or stirrup 1.6' t0 thelinnerend or edge of the. downwardly facing, horizontal shoulder 84. Saidinner end or edge Vof saidv horizontal shoulder 84 is parallel with theinner .surface of the strip of metal which constitutes the bracketmember or stirrup 18, and the beveled surface 85 lies in anobliquefplane including the inner end or edge of the horizontalshoulder. 84. The strip of metal constituting the bracket member orstirrup 16 is at the outer side of and parallel with the slab of metalcon?l stituting. the base of the bracket member or stirT rup 15, `andthe beveled surfaces 8U and 85. slant downwardly vand inwardly atsubstantially.v the same angle. The upper portionoi the bracket memberor stirrup 16. which provides the horizontal shoulder 84 and the beveledsurface 8.5.; is of .Wdthto be freely received between 4the spacedapart, oppositely disposed retaining and guiding elements 8l of thebracket member or stirrup 1.5:. A. gui'depin 86, fixed. in a .hollowpart -81- .of the j upper portion of said bracket member or ystirfrup,j16,;includes oppositeend portions 88, 88 of said guide pin disposedinthe opposite guideways 82,82, respectively, when the lower barrel 22is elevated, inoperative position.. y .Y lnFrigs.; 1, 2, 4.,. 5 and 6 ofthe drawings the downwardly facing, horizontal shoulder 84 dise dosedSeated upon the .upwardly facing, horiev zontalslioulder 19 to retainthe lower barrel 22 .in an elevated, inoperative position, as said lowerbarrel .is disclosed in Fig, 1. To release the-sup-A ported. ybraclfretmember or stirrup16 from .the supporting bracket member or stirrup 15,so that; the lower barrel ,22 can be moved toa depressed', operativeposition, all that is necessary is .to ele. Vateasad lower barrel Withinthe intermediate 'barrel .Z0 from the position o f the lower barrel.'@sin said Fig. 1 to position where the opposite endportions 88, .8.8 oftheguide pin 86 ride une wardly beyond the upper, free ends-of the resilient arms83. Clearly, said opposite end por! t'ons, 88 of said guidevpin 86 will cause said base of the bracket member .or stirrupS `in.:r.- sponse to elevation of the bracket member-,orstir- `rup 15., andwhen the guide pin 8,6 has-moved upwardly to. position above the upperends. of the resilient arms 83 these will spring back. to their normalpositions beneath said guide pin. When the lower barrel.- 22 is` moveddownwardly after moved upwardly to situate the. opposite end por,- tions88, 88 of the guide pin 86 clear ofthe upper, ree.=.ends of theresilient arms 83, said opposite end portions 88., 8.8 will ride clownover the outer surfaces of the smoothlycurved, outwardly and downwardly'extending resilientA arms. During such downward movement of the bracketmember or stirrup 16 the strip of metal which constitutes said bracketmember or stirrup will be flexed outwardly to cause the horizontalshoulder 84 to be clear of the horizontal shoulder 19. The con..-struction and arrangement are such that the opposite end portions 88, 88o f the guide pin 86.

Y 22 can be depressed or; moved downwardly to an resilient arms strobe'flexed outwardiyfrom tire 75 operative position. Said bracket member orstir.- rup 'i6 will spring back to its normal position when the oppositeend -portions 88, 88 of the guide pin 88 become released from the. lowerends of the outer surfaces ofl the retaining and guiding elements 8 l,as will be obvious. To again assemble the supported bracket memberA orstirrup 18 with the supporting bracket member or stirrup 15, so that thehorizontal shoulder 84 will rest upon the horizontal` shouldervls, allthat is necessary is to elevate the lower barrel 22 within theintermediate barrel 28. fromk a4 lowered or operative position of saidlower barrel to the position ofthe lower barrel as in Fig. l. Upon suchelevation oi the lower bar-rel the beveled surfacel 85 will slideupwardly over the beveled surface 8l) whilev the bracket memberv orstirrup 18 becomes flexed outwardly, and when said horizontal shoulderk8 1! reaches elevation just above said horizontal shoulder 19 theresilient potential of the strip of metal constituting said-.bracketmember or stirrup- 16 will causethe shoulders to become ine terengagedas disclosedinr Fig. 5. j

In Figs. 10 to 13of thedrawings there is'disclosed a modifiedmechanism,V represented gener-.- ally at 89, forreleasab-ly retainingthe lower barrel, such as 22, of anuptake pipe or conduit, such as I8,of an apparatus ofthe present character in an elevated, inoperativeposition.`

Said mechanism 8,9 includes, a Asupporting en. tity which is rigidly'xedupon the outer ,surface of an. upper portion of the intermediate barrel20 and a supported entity 9| which is rigidly Vxeol upon the outersurface of the upper portion of the lower barrel 2,2. The supportingentity; 88 is at the outer side ofthe uptake pipe or? conduity i8 andthe supported entity 3| lies in a space between said intermediate barrel28 and lower barrel 2'2. Said vsupporting entity 90 is at one side ofthe uptake pipe or conduit I 8, and said` supported entity 9|as-disclosed is in completely surrounding relation to the upper portionof lthe l to cause .the latch element 96, tobe'pushed out-y 93 of thecylinder 92 is contiguous with the outer surface of said intermediatebarrel and the outer end wall 94 of said cylinder 92 is in somewhatspaced relation to the intermediate barrel. A piston 95 snugly slidablein the cylinder 92 rigidly supports a latch element 96 disposedcentrally and longitudinally of said cylinder. The latch element 96projects from the side of the piston 95 adjacent the uptake pipe orconduit I8, and a portion of said latch element 96 spaced from saidpiston 95 is slidably guided, at 91, in the inner end wall 93. The inneror free end portion 98 of lthelatch element 96 extends through anopening 99 in the intermediate barrel 20 and is situated at the interiorof said intermediate barrel. The inner or free end of said latch element96'is constituted as an oblique or beveled surface I001which extendsupwardly and inwardly of the intermediate barrel. A coil spring IOI issituated within the small cylinder 92 at the side of the piston 95opposite the uptake pipe or conduit I8. One end of said coil spring I0|is -seated against said pistonv 95 and the other end of theV coil springis seated against the outer end wall 94. Normally, said coil spring |0Iurges the latch element 96 to position outwardly of the closed cylinder92 and inwardly of the intermediate barrel 20, about as disclosed inFigs. 11 and 12 of the drawings. A relatively ne opening |02 extendsthrough the piston 95 at one side thereof and a comparatively largeropening |03 extends through' said piston at the opposite side thereof.The ne opening |02' constitutes a passageway through which aircan seepor flow -slowly in either direction between the chamber |04 of thecylinder 92v at the outer side of the piston 95r and the chamber v|05 ofsaid cylinder 92 at the inner side of said piston.Y The larger opening|03 constitutes a passageway through which air can ow freely from thechamber |04 to the charnber'I05. 'A ap valve |05 vwithin saidchamber |05and normally covering the adjacent end Vof the larger opening |03 isadapted to preclude' passage of air through said opening |03 from the'vchamberI |05 to the chamber |04.

The supported entity 9| is constituted as van annular upper ring |01 xedabout the upper end of the lower barrel 22 and an annular lower rin'g|08 fixed about the upper end portionfof said lower barrel to provide anannular space |09 between said upper and lowerl rings into which the`inner, free end portion 98 of the latch element is adapted to extend.The upper edge portion I'I0 of the outer surface of the annular upperring- |01 is adapted to be engaged -against the oblique or beveledsurface |00 constituting the free, inner end of the latch element 96upon upward movement of the lower barrel 22'to :cause said latch elementto be pushed outwardly against the resilient action of the coil springIDI, and when said annular upper ring |01 has reached elevation abovethe latch element, so that said latch element is alined with the annularspace |09, said coil spring IOI is adapted to cause the free, inner endportion 98of the latch element to become'A seated beneath a downwardlyfacing, horizontaly shoulder III which the lower surface of the annularupper ring |01 provides, thus to cause the lower barrel 22 to beretained in an elevated, inoperative position, as it is shown in Fig.12. lThe upper edge portion I|2 of the outer surface of the annularlower ring |08 also is adapted to be;

wardly. Desirably, the lower Aring .|08 issomewhat thicker than the"upper, ring |01; While inward position within ythe intermediate barrel20, after outward actuation of said latch element,

it will be evident that'the return-` action will' beL slow. Theconstruction andv arrangement will be such that upon Iquick downwardmovement of the lower barrel 22 fromV position where, the upper engagedagainst said oblique or beveled' surface lpuponlupward movement'of thelower barrel` 221mmV its position as disclosed-,in said Fig. 12,

edge portion I|2 of thev outer surface of the an-Y nular lower ring |08is retaining vthe latch 'element 96 in position outwardly of theintermediate barrel 20, the downwardly facing, horizontal shoulder I|will be caused to travel downwardly past the elevationof said latchelement, 96 before the coil spring IGI, limited'in its action by the'neness of the opening |02, will havehad tiineyto return the latch.element to position where it could situate itself beneath saidhorizontal shoulder III.

In Figs. 11 and 12 of the drawings fthe-down wardly facing, horizontalshoulderA is dis-l closed seated uponthe inner, vfreeend portion 98 ofthe latch element 96 to retain the lower barrel 22 in an'elevated,inoperative position, as said lower barrel is disclosed in Fig. 10. 'Torelease the supported entity 9| Afrom the.' supporting en'-,v

semble the supported entity9| with the supporting entity 90, so that thehorizontal shoulder II will rest upon the latchv element 96, all thatneed be done is to elevate' the klower barrel from alowered or operativeposition .to position where the annular space |09 is alined with thelatch telement 96 andtoretain said lower barrel in posi` tion uwheresaid annular space is in alinement with said latch elementfor asuflicient, relatively shortV interval of time to permit the latchelement, pushed outwardly by upward movement of the upper ring |01, tobecome situatedwithin the annularspace. f

Thev apparatus 'includespmechanism'for con-v trolling a cover I I3 forthe upper barrel'I 9 of the uptake pipe or conduit |8 in such mannerthat said cover can'beretained in the open and in the closed condition'of said uptake pipe orconduit.I

Said cover is adapted tobe closed at'all times when the apparatus isoutof 'use and is adapted normally tobe open when a `locomotive smokelstack is situated in operative position relatively to the apparatus.Means is included,'however,

through the''instrumentality of which the cover` ||3 can be moved to andretained in the'clo'sed condition ofthe uptake pipe or conduit whilethis is assembled with a locomotive' smoke stack.

As disclosed, the coverl I I3 is pivoted, at the right side of theuptake pipe or conduit in Fig. 1," upon the upper portion of the upperybarrel I9 and in' cludes a protruding arm I I4 carryin'g a weight' ||5of suilicient magnitude to'move said cover to open position. A cord orwire I I6 has its upperv end attached'to the cover II3 at the side ofits pivot opposite the weight |I5, and its lower end attached, as at|I1, to a free end-portionof a control lever ||8 for said cover. Saidcontrol lever II8 is of at, generally triangularconfguration, and ispivotally supported, at location in spacedrelation to the cord or wire II6 andadja-4 cent the lower edge of the control lever, upon the crosspin2|.. A second cord` or wire II9 has` its upper end attached, as at |20,to the control lever i I I8 lat location 'intermediate the cord or wire|6 i and the cross pin 2| and its lower end attached,

as at |2|, to a freevend zportion of an actuating lever |22 for thecover ||3. Said actuating lever l |22 has its intermediate portionpivoted, as at' 1 |23, upon the annular metal strap 1|, and an end gportion |24 yofV the actuating lever |22, at'the side the end portion|24 of the actuating lever |22.

, The construction and arrangement are such that upon elevation of thelower barrel 22 from a lowi ered or operative positionr to the elevated,inoperative'position as inFig. 1, the actuating element |25 engages andswings upwardly the end portion l |24 of the actuatingY lever |22, thusto cause the 1 cord or wire H9, the control lever A| |-8 and the cord orwire ||6 to'be moved downwardly and f the cover ||3 to be moved'toclosed position over i the upperbarrel I9. As will be apparent, theactuating element |25'is engaged with the free end i of the end portion|24l of the actuating lever |22 i in Fig. 1 to positivelyretain thecover I3 in the` closedc'onditionofftheuptake pipe or conduit I8.

Evidently,upon downleased from said intermediate barrel 29, saidv actuatingelement v|25 will `first slide downwardly` d along thefree endA and thelower edge' of the end'v portion |24 and later be removed from engage'-vment with said end portion |24. Upon release of the actuating'lever 22by the actuating ele.-

ment^|25, the weight ||5 obviously will' act to move'the coverI ||3 toopen position. That'is,

as at |32, to a 'portion' ofthe control lever ||8 above the crossl pin2|, and the other end of the` cableisv attached, asat |33,to the freeendpor-L tion of a closing lever |34. Said closing lever |34l is adaptedto be pivotally supported, as at |35,:

vupon a fixed part in the roundhouse, and-,an intermediate part of theclosing lever. is situated beneathV a guide and clamp |36 for saidclosing lever. Clearly,4 by swinging the closing lever |34 downwardlythe cablelll is actuated to swing the controlflever L| |8 downwardlythus to move the cover ||3 to closed position. The guide and clamp |36is adapted to stably retain the closv ing lever '|34 "at theposition inVwhich disclosed,l in Fig. 1. lWhen said closing lever is swung 11p--Wardly the weight -I |5causes the vcover |3.to bei F moved to openposition unless held .closed byjthe l actuating element |25.,I` A y f Anexhauster for'the uptake pipev or conduit I8 may consist .of a usual orpreferred type of fan-or blower |31 kactuated by a suitable motor |38,iboth shown situated upon the round house roof. The fan or blower |31 issuitably-,and con` veniently assembled with the upper barrel 1.9. k

`Supposing the lower barrel 22 of the uptake pipe or conduit I8 toI bein elevated, inoperative position as ldisclosed in Fig. l of thedrawings` and it is'desired to associate a locomotive smoke stack withthe element 56 of said uptake :pipe or conduit, all that is necessary tobe done to accomplishfthis result is to actuate the compound valve 31ofthe multiple-valve unit 60 so that the intermediate barrel 29 and therlower barrel 22 are swung as a unit to position Where said' element 56is in'vertical alinement with the-smoke stack andv to actuate thecompound valve. 31 .of the multiple-.valve unit 35 ysothat said lowerbarrel is moved first upwardly and then'downwardly.Y

To 4return'the` lower barrel 22 to elevated, inoper.y ativefposition allthat'is-necessary is to actuate said compound valve 31 of said.multiple-valve. unit 35 so that said lower `barrel is moved upewardly.It willv be apparent that the intermedi-y ate'barrel 29 and the'l'owerbarrel 22 vcan be either vertically disposed, as in full lines in Fig.1, orobliquely disposed, as in dotted lines in said Fig.Y '1, when saidlower barrel is in elevated, in. operative pOsition.' v 1 sl The mannerin which causes the piston 29 to be moved along the cylin.

der' 28, intheinstance of each yfof the cylinderwith-piston devices 26,21 and 59, will be obvious from the full description hereinbefore made.Inf

the case of each of said devices 26, 21and 59 the piston 29 is fcausedlto' bey stationary, whenthis is intentional, by manipulating thecorrespond-Av v ingcompound valve 31 tofshut 01T communicaf' tionbetween the port 38 `and both of the 'ports' 39,'4|, as well as to shutoff communication be; tween the port 4|] and both of said ports 39,-4|..-

This can be accomplished 'bylotaling Said 00116y sponding compoundvvalve to position where its oppositely disposed ihigh parts'aresituated gin.l closing relation to either the oppositely arranged ports38, 40 or theoppositely arranged ports 39;

4|. The compound valve 3,1 evidently'is -con= structed, in the instanceof each of the multiple;

valve units 35 and 66, to preclude passage of;v lluid directly from theport 38 tothe port 40,-as'f well as to preclude passage of uid directlybe-,V tween the ports 39 and 4|.

The utilization of raising and lowering having saiduptake pipe orconduit, andthe con'- struction and arrangement as illustrated anddescribed makes provision for variations in thevv heights of locomotivesmoke stacks, as well as for variations from vthe vertical asmay becaused by broken springs.
